Abnormal steroid sulfate in plasma of women with intrahepatic cholestasis of pregnancy.

Concentrations of numerous sulfate steroids were checked in the plasma of 10 women in normal pregnancy (NP), 21 women with intrahepatic cholestasis of pregnancy (ICP) and 10 pregnant women suffering from viral hepatitis with jaundice (VHP). A considerable increase in 5 alpha pregnane and 5 beta pregnane 3 alpha, 20 alpha diols, mono- and disulfates and in 5 alpha pregnane 3 beta, 20 alpha diols disulfates was observed only in ICP and not in VHP. This observation permits us to hypothesize that these hormone changes can have a causative role in the pathogenesis of ICP.
